Presented by: Street Cop Training

June 7, 2023


$225/ student




The Unmasking Hidden Facial Expressions Course was designed to provide law enforcement with

the tools to perform an aspect of policing that is severely lacking: Recognizing different types of

facial expressions. Course content is based on scientific research that has been around for

decades but unfortunately has been slow in making its way into the law enforcement community.

This course will teach officers how to articulate the elements of the 7 universal emotions in the

face and how to a recognize them when they occur in micro-facial and subtle facial expressions.

Facial expression movements will be explained in a manner that is not only understandable but also

will ensure that the officer attending is engaged. Attendees will learn how to recognize facial

expressions that flash on the face between 1/25th and 1⁄2 second. During this class the officer will

be instructed on emotions, the facial expressions themselves and how knowledge of the facial

expressions can be used to assist in evaluating truthfulness and detecting deception.

This course has been designed for everyone in law enforcement, as it has been taken by patrol

officers, agents, investigators, conservation officers, sheriff’s officers, arson investigators,

detectives and other LEOs on the local, state, and federal levels with various job titles and job
